SLSBMB AI vs an outbound agency
SLSBMB AI does the work of an outbound agency — research, every email, verified contacts, the sending infrastructure and reply sorting — as a product with public prices. The same monthly budget runs several times the inboxes, emails and new people a typical agency setup does.

Side by side
| Typical outbound agency | SLSBMB AI | |
|---|---|---|
| Price | $2,500–$10,000 a month on retainer for most cold email programs, $3,000–$7,000 typical; $11,000–$19,000+ for premium programs; SDR teams and campaign pods from about $8,000 to $30,000 | $500 one-time for the researched playbook (launch price), then a Sending Engine budget from $800 a month; contacts alone at $0.10 per verified email |
| What the retainer covers | Often 60–70% of the real spend: domains, mailboxes, data and warmup add $500–$2,000 a month | Everything: domains, inboxes, authentication, warmup, verified contacts, campaigns and reply sorting are in the budget |
| Setup | Onboarding fees of $1,500–$5,000 are common | No setup fee |
| Contract | Usually a three-month minimum; some retainers are fixed for 3–6 months | Month to month; turn renewals off at any time |
| Sending capacity | A typical setup is 6–15 inboxes per client at 25–30 emails each a day | 40 inboxes at $3,000 a month, 112 at $5,000, 400 at $10,000 |
| Research and copy | Done by the agency's team; how much you see varies | The AI Outreach Playbook: every audience with its evidence and size, and every email — yours to read before anything is sent, and to keep |
| Consistency | Depends on the people assigned to your account | No people to vary: every client gets the full methodology at full depth |
| Visibility | Reports on the agency's schedule | Your private SLSBMB AI workspace: campaigns, replies, CRM, audience by audience |

The same money, side by side
| Monthly budget | At an agency | In the SLSBMB AI Sending Engine |
|---|---|---|
| $3,000 | Most programs cost $3,000–$7,000 for a 6–15 inbox setup, plus $500–$2,000 for infrastructure and data | 10 domains, 40 inboxes, 13,200 campaign emails to 4,400 new people a month |
| $7,000 | Belkins email-only campaigns start at $6,500 | 48 domains, 192 inboxes, 86,400 campaign emails to 17,280 new people |
| $8,000 | SalesHive: one US SDR on phone and email, 250+ touches a day | 61 domains, 244 inboxes, 3,660 campaign emails a day to 26,840 new people a month |
| $12,000 | SalesHive: two US SDRs, 500+ touches a day | 125 domains, 500 inboxes, 7,500 campaign emails a day to 55,000 new people a month |
| $15,000 | Callbox: one campaign pod costs $15,000–$30,000 | 166 domains, 664 inboxes, 219,120 campaign emails to 73,040 new people a month |
Every Sending Engine figure includes the verified contacts, the infrastructure and its warmup, with no setup fee and each month paid separately. The full ladder is on the pricing page, and what cold email costs adds tools, AI SDRs and in-house hires.
Why the same money goes further
An agency's retainer pays for people: strategists, copywriters and SDRs, their tools and the agency's margin on their hours. Output depends on who is assigned to your account, and capacity grows only as fast as the agency can staff it.
SLSBMB AI pays for machine output. PROXY, our AI interviewer, briefs a team of specialist AI agents — a researcher, a copywriter and a targeting specialist — that work from a 30,000-word methodology refined through more than 300 revisions. One playbook takes 30–47 million tokens of AI work; a chatbot answer takes a few thousand. The published Revopush playbook holds 19 audiences, 57 finished emails and 21,469 targeting searches. Because no one has to be hired to add capacity, the Sending Engine adds domains and inboxes in proportion to the budget, and the price of an email falls from about $0.303 at $800 a month to $0.076 at $10,000.
Results
- On the earlier version of this engine, SLSBMB delivered hundreds of replies for B2B clients within two months. The methodology and the engine have been rebuilt and strengthened several times since.
- A client on the entry engine, with 8 inboxes, received leads within the first days of sending.
How the work is split
SLSBMB researches the market, writes every email, finds and verifies the contacts, runs the sending infrastructure and reads every reply. Auto-replies, bounces and unsubscribes are filtered out, and the people who want to talk land in your SLSBMB AI inbox and CRM — you hold the sales conversation with someone who has already answered.
SLSBMB runs email. Teams that also want phone calls or LinkedIn steps add them alongside; the playbook and the contacts are yours to use in any channel or tool.

How does SLSBMB plan results?
For planning we assume about 2% of campaign emails get a reply at full capacity, from the start of month three — at $3,000 a month that is about 264 replies over 22 sending weekdays. Your workspace reports activity and replies audience by audience, so the strongest audiences show themselves.
